PURPOSE:To heighten the resistance of a tire to wear and wet skid, by providing a carcass for reinforcing the sidewall and the tread and by bending each lateral section of the carcass upwards around a bead ring and providing a rubber filler and a reinforcing cord layer between the bent and the central sections of the carcass. CONSTITUTION:In a tire, a pair of sidewalls 2 and a tread 3 are reinforced by a carcass 4 made of at least one ply in which organic fiber cords are arranged. Belts 7-1, 7-2, which are made of plural cord plies of prescribed elasticity modulus and in which the plies are laminated together so that the cords cross with each other in directions different between the plies, are provided between the tread 3 and the carcass 4. Both the lateral sections of the carcass 4 are bent upwards around bead rings 5. A rubber filler 8 of prescribed hardness and a reinforcing cord layer 9 are provided between the bent section 6 and the central section of the carcass 4. At least one of the heights h1, h2, h3 of these portions 8, 9, 6 is equal to about 60% of the height H of the sidewall 2. |
